Abstract
A field experiment was conducted during Rabi 2021 at ICAR-KVK, Bengaluru RuralDistrict to study the influence of soil application of boron in STCR approach on soil properties,nutrient uptake, growth and yield of maize. The experiment was laid out in Randomizedomplete Block Design (RCBD) with nine treatments replicated thrice. The results revealedthat STCR integrated (90 q targeted yield) with 10 kg ha-1 borax as soil application hassignificantly increased the plant height (194.20 cm), number of leaves (14.20), cob length(19.50 cm), number of rows per cob (19.00), number of kernels per row (34.25) and 100 seedweight (34.87 g), kernel yield (92.60 q ha-1) and stover yield (114.32 q ha-1). Similarly, higheruptake of nitrogen, phosphorous, potassium and boron (287.13 kg ha-1, 62.78 kg ha-1, 229.38kg ha-1 and 2432.36 kg ha-1 respectively) were recorded in STCR integrated (90 q targeted
yield) with 10 kg ha-1 borax as soil application. Higher benefit cost ratio (3.14) and value costratio (6.71) was recorded in STCR inorganics (90 q targeted yield) with 10 kg ha-1 borax assoil application. Application of STCR based integrated nutrients with soil application of boronhelped in enhancing the growth and yield of maize to achieve the targeted yield (90 q ha-1).
